Have tried to use adapter with Sony nex5. Purchased the Nikon adapter and even though lenses connect OK the nex 5 keeps saying put lens on correctly. tried the only way it can go and nothing seems to change it. help.

Try going to the set up menu, go down several items till you get to "Release w/o lens," and enable this. This allows the shutter to work without a lens (which is what the camera thinks when there is an adapter in place).

Your 50 f/1.8 will still open to f/1.8, but due to crop factor will function as a 75mm on the NEX camera. Note that the crop factor also affects the *appearance* of DOF, so f/1.8 on a APS-C camera will look more like ~f/2.5 (-ish) on a full-frame camera.

I have the same Sony Nex5 and this len works as a charm. Just to make sure, this is a prime len, so there is not zoom on it, how ever the F value is pretty better than the stock (at least in my case) 18-55mm len

There are 2 versions for the NEX cameras, EA and EA2 which shown here. The EA is just an adapter for the A mount lenses. EA2, you get all the controls and metering available from the lenses. I've had two of the EA2 for my NEX7 and 5N. Worked very well.

As with any DSLR type camera with multi-use lens, check the information on the lens attached to the NEX-5N - it should indicate the thread size of 49mm. For any lens attachment always check the tread size before ordering.

This adapter has a removeable '1.4X teleconverter (infinity adapting) supplemental lens' insert. When I use the adapter WITHOUT it's supplemental lens on my D5100, I need to calculate the camera's compressed sensor value for a full frame lens! IE.: 50mm fullframe lens to my camera's compressed sensor, with the adapter's supplemental lens NOT IN place, is (50mm x 1.5 = 75mm) ~~~infinity focus is weak When I use the adapter WITH it's supplemental lens on my D5100, I need to calculate the camera's compressed sensor value for the full frame lens! IE.: 50mm fullframe lens to my camera's compressed sensor, with the adapter's supplemental lens IN place, is (50mm x 1.4 = 70mm) ~~~infinity focus is strong

this is a lens adaptor that will mount a different lens to your camera. I use an older canon prime lens on my sony a57. This unit does not fit well but is manageable. Can only use on manual- no auto focus. Will remove from your camera and lens you are using it with.

Look at your lens (or Google it) to see the thread count. It should say something like 5.8 or 58 which is 58 mm. Some have 37, some have something different. If you need to use an adapter, you're buying the wrong size (thread count) to begin with. You'll get better picture if you buy proper fitting lenses and avoid adapters.

Hi! NEX-7 cameras uses E-mount lenses (e.g. SEL1855) in which if you have an A-mount lens (SAL1855) you needed an adaptor to make it work. You may use the Sony A-mount to E mount lens adaptor (LA-EA) and currently there are 4 available varieties for this adaptor. You may check on the link below for a detailed information that will suit your preferences. Hope this helps.

I have both lenses. Are different lenses for different uses. With the 50mm 1.8 you can get a great bokeh to 1.8. (In my opinion the great problem for this lens is the quality of imagen is not good in the edges at 1.8). The 50 mm 1.8 is perfect for begins in the bokeh. Personally, I bought the 40mm 2.8, because is the smallest lens in the market. I can carry my camera with this lens every where. This lens (40mm) has a great quality of imagen from 2.8 to 22. If you look for a lens for portrait, buy 50 mm. If you look for a compact lens with excelent quality, I recomend 40mm.

Your question does not quite make sense but if you have a rotating ring to change the aperture with the adapter you can fit the adapter and use another brand body. Your lens will be fully manual, both focus and aperture. Your camera aperture control becomes disabled.

Actually no, this one is a prime lens with a maximum aperture of 1.8 while the 18-55 is a wide lens with a maximum aperture of 3.5 (at least the one I have, which is a DA L 18-55 Pentax lens).

Cindy,I purchased an EA1 adapter and returned it. Although it was a nicely constructed adapter it caused me to loose 1F stop from an already slow lense and it did not carry forth full auto focus capabilities, only auto exposure. I'm still searching for better options. These appear to be the differences:AE1- Converts Sony A/ Minolta mount to E mount. Auto exposure but no or limited auto focus. AE2- Converts Sony A/ Minolta mount to E mount. Auto focus, auto exposure w/ transluecent mirror.AE3- Same as AE1 but updated model.AE4- Same as AE2 but updated modelIf you really want an EA 1 or 2 there are other internet suppliers that still have these in stock.

On an APS-C NEX it will be 1.5 x focal length, so it'll be 28.5mm. I actually carry this one more often than my Sigma 30mm.

Actually, a SMALLER APERTURE would have a HIGHER NUMBER...like f/11. The f/numbers are FRACTIONS, so a bigger number is a smaller aperture, and a smaller number is a bigger aperture...just a 1/2 OF AN APPLE PIE (f/2) IS BIGGER THAN 1/8 OF APPLE PIE (f/8).To get a smaller aperture (the hole the light enters), you need to pay more money, and get a lens with a bigger aperture number...like f/8, f/11, or f/22.I have seen many f/2.4 lenses (notice the decimal point between the 2 and the 4). I have never seen, or heard of, an f/24 lens...but I suppose someone may make them. There are f/22 lenses available. Actually, a SMALLER APERTURE would have a HIGHER NUMBER...like f/11.

Yes, it will allow those lenses to be mounted on an NEX-5n. However, you need to be aware that it does not make any electrical contact between the body and lens. Newer "focus by wire" lenses will not work as they need power from the camera to focus. If the focus ring on your lenses has stops at either end of travel, you will be able to focus using this adapter. If the focus ring on your lenses will turn indefinitely in the same direction then the lenses are focus-by-wire and you will not be able to use this adapter.

Yes - The Fotodiox adapter works well for that application. I have been using all of my old Minolta lenses (especially 50mm f1.4 and 50mm macro) on my Nex 5N. Make sure you set the menu to allow shutter to release "without lens". Use Manual or Aperture priority setting for metering and Focus Peaking to assist in focusing. You will have to manually set aperture on lens as there is no electronic communication with body

No, I actually have the telephoto lens and it fits lens with 49 mm thread size with the adapter ring or 52 mm without adapter. My Sony nex-3N lens thread size on the kit lens is 40.5 mm.
